Development of the indusium griseum. III. An autoradiographic study of cell production

An autoradiographic study of neuronal and glial production was carried out in the indusium griseum of mice. Most neurons were produced between 13 and 15 days post-conception. One part of the glial population underwent its last or second-last divisions between 14 and 16 days post-conception, while the other continued to undergo a number of divisions into postnatal life. It is suggested the former were astrocytes and the latter oligodendrocytes.
